Using some nice YouTube videos from the SDRUNO crowd, I was able to configure my next generation SDR receiver to the Mag Loop and experience the mystery and joy of configuring WSJT-X, after some more YouTube of course.

Chapter 13 Maxwell’s Equations and Electromagnetic Waves
web.mit.edumagnetic field can be obtained by using Ampere’s law: ∫Bs⋅=dµ0eInc GG v (13.1.1) The equation states that the line integral of a magnetic field around an arbitrary closed loop is equal to µ0eI nc, where Ienc is the conduction current passing through the surface bound by the closed path. In addition, we also learned in Chapter 10 that, as a

www.topbandhams.cominefficient antenna produces a small-amplitude EM wave for the same feed power, and converts most of the power into heat. Generally people don't think of radio-frequency radiation in terms of discrete particles (oscillating electrons and photons) -they typically use the wave model instead, as it's much easier to use.
